Chip Carrying Tray

ABSTRACT

A chip carrying tray comprises plural rectangular flat carrying portions for carrying plural chips. Each of the carrying portions is provided with stopping walls for restricting the slippage of the chip. The stopping walls are defined with through holes for discharging moisture of the chip carrying tray. By such arrangements, the chip carrying tray can stably carry the chips and substantially keep the chips dry.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a semiconductor carrying device; and more particularly to a chip carrying tray.

2. Description of the Prior Art

Referring to FIGS. 1-2, a conventional chip carrying tray A comprises plural matrix-arranged carrying portions A1. Each of the carrying portions A1 includes four stopping walls A2 around a periphery thereof. Chips X are placed in the respective carrying portions A1 and restricted by the stopping walls A2. Further, each of the carrying portions A1 is defined with a through hole A3 for discharge of moisture from the chip carrying tray A to keep the chips X in the chip carrying tray A dry. However, each of the chips X includes plural solder balls X1 on a bottom thereof, when the chips X are placed on the respective carrying portions A1, the solder balls X1 will be brought into contact with the through holes A3 of the carrying portions A1, and thus the edges of the through holes A3 are likely to scratch or damage the solder balls X1.

Referring to FIG. 3, another conventional chip carrying tray B comprises plural funnel-shaped carrying portions, and each of the funnel-shaped carrying portions includes four inclined surfaces B1 and a through hole B2, so that the carrying tray B can also have a ventilation function, and the chips X will not be brought into contact with the edges of the through holes B2, thus avoiding the occurrence of scratch and damage to the solder balls X1. However, the carrying portions are funnel-shaped and non-planar, so that the chips X must be moved with much carefulness in order to be stably placed on the carrying portions, or else they are prone to inclining and scratching the solder balls X1 of the chips X.

The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide a chip carrying tray which can stably carry the chips and substantially discharge the moisture to keep the chips dry.

In order to achieve the above objective, a chip carrying tray in accordance with the present invention comprises plural matrix-arranged carrying portions. Each of the carrying portions is used to carry one chip and provided with two opposite first stopping walls and two opposite second stopping walls. The first and the second stopping walls are alternately arranged. Each of the second stopping walls is defined with a through hole.

The stopping walls are used to restrict the slippage of the chips, and the through holes of the stopping walls serve as the channels for discharging the moisture of the chip carrying tray to keep the chips dry.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.

Referring to FIGS. 4-7, a chip carrying tray 100 in accordance with a preferred embodiment of the present invention comprises plural matrix-arranged carrying portions 10. Each of the carrying portions 10 is rectangular and flat and provided for carrying one chip X. Each of the carrying portions 10 is further provided with two opposite first stopping walls 20 and two opposite second stopping walls 30 around a periphery thereof. The first stopping walls 20 and the second stopping walls 30 are alternately arranged, and the first stopping walls 20 are higher than the respective second stopping walls 30. Each of the second stopping walls 30 is further defined with a through hole 31 in a direction vertical to the carrying portion 10, and each four connected carrying portions 10 define a through hole 40 therebetween.

The chip carrying tray 100 can carry plural chips X. The chips X can be stably placed on the flat carrying portions 10. The stopping walls 20, 30 are used to restrict the chips X in the respective carrying portions 10. The through holes 31 of the respective second stopping walls 30 and the through holes 40 between the respective carrying portions 10 serve as air channels to allow the moisture to be discharged from the respective through holes 31, 40, keeping the respective chips X dry.

As shown in FIG. 6, the through holes 31 of the respective second stopping walls 30 can also be defined in the direction parallel to the respective carrying portions 10 to achieve the same function as described above.

When the chips X need carrying, plural chip carrying trays 100 will be piled up one upon another as shown in FIG. 7. When the plural chip carrying trays 100 are piled up, since the first stopping walls 20 are higher than the second stopping walls 30, a clearance D1 will be formed between each two neighboring chip carrying trays 100. The height of the clearance D1 equals the height difference between the first stopping walls 20 and the second stopping walls 30, so that after the chip carrying trays 100 are piled up, the clearances D1, the through holes 31 of the second stopping walls 30 and the though holes 40 can completely discharge the moisture. Therefore, even though the plural chip carrying tray 100 are piled up, the chips X in the chip carrying tray 100 can also be kept dry.

Further referring to FIGS. 8 and 9, the first stopping walls 20 of the chip carrying tray 100 are as high as the second stopping walls 30, and the chip carrying tray 100 is further formed with a base 50 around an outer periphery thereof. The base 50 includes a piling space 51 in a bottom thereof. When plural chip carrying trays 100 are piled up one upon another, one of each two neighboring chip carrying trays 100 will be partially disposed in the piling space 51 of the base 50 of the other of the two neighboring chip carrying trays 100, thus forming a ventilating space D2 between each two neighboring chip trays 100 to discharge moisture to keep the chips X dry. Further, the base 50 is formed with a protruding ear at one side thereof, so that the user can move the chip carrying tray 100 conveniently.

While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
